[susu] 获取按钮详情失败

Error message

[susu] 获取按钮详情失败: %w

What it means

Terminal wrapper in susu getButtonDetail: doRequestWithRetry exhausted MaxRetries attempts for the button-detail POST. The cause is the last transport error or non-200 status seen during those attempts.

Solutions

1. Inspect the wrapped cause (transport vs status)
2. Slow down retries — this endpoint is rate-limit sensitive
3. Cache negative results briefly to avoid hammering on repeated failures
